If it's a theory, how can anyone say for a fact whether it's true or not? That's why it's a theory. Like the big bang. Only that's true because it happend one night in the 70's backstage at a Led Zeppelin concert. Just ask the shark that was there.

Anyways, I sure as hell don't believe in the big bang theory. There's no proof. Evolution, on the other hand, is a different thing all together.

Plenty of proof for Big Bang. Among the experts, that there was a "Big Bang" [a "singularity" of a certain sort] is not in question. The interesting questions revolve around matters such as: will the universe keep expanding? will there be a contraction phase? etc.

And I can assure you that the evidence is overwhelming. It's a bit empty to say there's no proof - red shifts of galaxies, background 3K radiation, etc. Start reading!
